Greenlet package is a spin-off of Stackless, a version of CPython that supports micro-threads called "tasklets". Tasklets run pseudo-concurrently (typically in a single or a few OS-level threads) and are synchronized with data exchanges on "channels".

Schedule is an in-process scheduler for periodic jobs that uses the builder pattern for configuration. Schedule lets you run Python functions (or any other callable) periodically at pre-determined intervals using a simple, human-friendly syntax.

CLI Helpers is a Python package that makes it easy to perform common tasks when building command-line apps. It's a helper library for command-line interfaces.

The ratelimiter module ensures that an operation will not be executed more than a given number of times during a given period.

This package provides a way to monitor file system events such as a file modification and trigger an action. This is similar to inotify, but portable.

JSON (JavaScript Object Notation) is a subset of JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data interchange format.

Simplejson exposes an API familiar to users of the standard library marshal and pickle modules. It is the externally maintained version of the json library contained in Python 2.6, but maintains compatibility with Python 2.5 and (currently) has significant performance advantages, even without using the optional C extension for speedups. Simplejson is also supported on Python 3.3+.

autoflake removes unused imports and unused variables from Python code as reported by pyflakes.

By default, it only removes unused imports for modules that are part of the standard library. Removal of unused variables is also disabled by default. It also removes useless pass statements.

This library helps to validate configuration files and produce human readable error messages.

This package provides a final implementation of JSONPath for Python that aims to be standard compliant, including arithmetic and binary comparison operators, as defined in the original JSONPath proposal.

Sexpdata is an S-expression parser/serializer. It has load and dump functions like pickle, json or PyYAML module.

This package makes it easy to draw tables in terminal/console applications from a list of lists of strings. It supports multi-line rows.

This package provides a Python library that is an implementation of traditional readability measures based on simple surface characteristics. These measures are basically linear regressions based on the number of words, syllables, and sentences.

This is a Python library for color math and conversions.

This package provides a parser, schema validator, and data binding tool for YAML and JSON.

path (formerly path.py) implements path objects as first-class entities, allowing common operations on files to be invoked on those path objects directly.

This package provides a python port of YUI CSS Compressor.

This package contains a small collection of test tool plugins for nose2 and flake8.

This package contains a collection of plugins for markdown-it-py like:

1. amsmath,

2. attrs,

3. container,

4. definition list,

5. dollarmath,

6. field list,

7. footnote,

8. textmath, and

9. wordcount.

The aim of the decorator module is to simplify the usage of decorators for the average programmer, and to popularize decorators usage giving examples of useful decorators, such as memoize, tracing, redirecting_stdout, locked, etc. The core of this module is a decorator factory.

This package lets you read image and metadata from many bio-scientific formats such as plain TIFF, BigTIFF, OME-TIFF, STK, LSM, SGI,NIH, ImageJ, MicroManager, MD GEL, and FluoView files. It also lets you write numpy arrays to TIFF, BigTIFF, and ImageJ hyperstack compatible files.

The typing_inspect module defines experimental API for runtime inspection of types defined in the Python standard typing module.

This package provides efficient Python bindings to picosat on the C level. When importing pycosat, the picosat solver becomes part of the Python process itself. picosat is a Boolean Satisfiability Problem (SAT) solver.

Pebble aims to help manage threads and processes in an easier way. It wraps Python's standard library threading and multiprocessing objects.
